Milling and/or grinding tool and turning process using a milling and/or grinding tool

Abstract

Milling and/or grinding tool, in particular a dental milling tool or dental grinding tool (10, 100), comprising a shaft (12, 120, 140) and a working part (14, 140), wherein the working part (14, 140) has at least one partially ball-shaped end face region (20, 200) and a section (18, 180) tapering toward the end face region (20, 200), in particular a conically shaped section, wherein the end face region (20, 200) comprises geometrically defined and/or geometrically undefined cutting edges (80a, 80b, 91) and wherein the working part (14, 140), in particular the tapering section (18, 180), comprises a first region (18a, 180a) with geometrically defined and/or geometrically undefined cutting edges (80a, 80b, 91) and at least a second, non-cutting region (18b, 180b), wherein the tapered section (18, 180) is configured such that it can remove a first time chip volume (ZSV1) and the end face region (20, 200) is configured such that it can remove a second time chip volume (ZSV2), and wherein the first time chip volume (ZSV1) is greater than the second time chip volume (ZSV2) at the same rotational speed (nF) of the milling and/or grinding tool.
